Question

Please solve these question
12.0 g of urea is dissolved in 1 litre of water and 68.4g of sucrose is dissolved in 1 litre of water the relative lowering of vapour pressure of ureasolution

Answer 1

Explanation:

Moles of urea =6012=0.2

Moles of urea =6012=0.2Moles of sucrose =34268.4=0.2

Moles of urea =6012=0.2Moles of sucrose =34268.4=0.2Both are non-electrolyte hence lowering of V.P. will be same.
